# Add CLItrail to Mintlify

Where the CLItrail tag goes in Mintlify, in its own idiom, with the consent, CSP and client-side routing details and how to check it works.

Written for Mintlify (hosted docs)

## Where the tag goes

Edit `clitrail.js in your docs folder (next to docs.json)`. Put the tag on every page that shows your install command; site-wide is best, after your existing analytics tags.

```js
// Mintlify runs every .js file in the docs folder on every page.
(() => {
  if (document.getElementById('clitrail')) return;
  const tag = document.createElement('script');
  tag.id = 'clitrail';
  tag.src = 'https://YOUR_SERVICE/browser.js';
  tag.dataset.website = 'YOUR_WEBSITE_ID';
  document.head.append(tag);
})();
```

## Only after consent

Use this file instead of the one above: it defines `startClitrail()`, which adds the tag once your consent manager reports consent.

```js
// Loads CLItrail only after the visitor agrees. Call startClitrail() from your
// consent manager's "accepted" callback; nothing is fetched or stored before that.
window.startClitrail = () => {
  if (document.getElementById('clitrail')) return;
  const tag = document.createElement('script');
  tag.id = 'clitrail';
  tag.src = 'https://YOUR_SERVICE/browser.js';
  tag.dataset.website = 'YOUR_WEBSITE_ID';
  document.head.append(tag);
};
```

## Client-side routing

Mintlify runs custom scripts once the page becomes interactive. The script adds the tag once, so the first page a visitor opens is recorded: the landing page, which carries the campaign.

## Content Security Policy

Mintlify serves the pages. If you put a Content-Security-Policy in front of them (for example through your own proxy), add `https://YOUR_SERVICE` to `script-src` and `connect-src`, and `blob:` to `worker-src` (only Safari before 26 needs that one).

```
script-src 'self' https://YOUR_SERVICE;
connect-src 'self' https://YOUR_SERVICE;
worker-src 'self' blob:;
```

## Verify it works

1. Deploy the docs (or run `mint dev`, http://localhost:3000).
2. Open a page with the tag in Chrome or Firefox (accept analytics first if you gate CLItrail on consent), open the developer console and run `await InstallAttribution.ready`. It resolves to `{ ok: true, urlId, hasAnalyticsContext, expiresAt }`.
3. In the CLItrail dashboard, open Visits & identities: the visit is listed.
4. Anything else names the cause: `disabled` (no consent yet, or `data-enabled="false"`), `opfs_unavailable` (the page is not served over https or from localhost), `Error` (the service refused the visit: add the page's origin, including a development origin such as `http://localhost:3000`, under Settings → Additional domains). If `InstallAttribution` is undefined, the tag did not load: check the Network tab and your Content-Security-Policy.

Then run your installer on the same computer and check **Install events**, or run the hook with [`--doctor`](https://clitrail.com/docs/doctor).

> Tip
> 
> Point campaign links straight at your install page: the first page a visitor opens is the one recorded, with its campaign. If `InstallAttribution.ready` is undefined after you deploy, use the [manual start](https://clitrail.com/docs/frameworks/mintlify#if-a-visit-is-not-recorded).

## If a visit is not recorded

Start the SDK yourself: this adds the tag without `data-website` and calls `InstallAttribution.init` once it loads.

Manual start

```js
(() => {
  if (window.InstallAttribution) return;
  const tag = document.createElement('script');
  tag.src = 'https://YOUR_SERVICE/browser.js';
  tag.onload = () => {
    const sdk = window.InstallAttribution;
    sdk.ready = sdk.init({ service: 'https://YOUR_SERVICE', project: 'YOUR_WEBSITE_ID' });
  };
  document.head.append(tag);
})();
```

## Notes

- Mintlify cannot put attributes on a `<script>` in `<head>`, so the file creates the tag itself, with `data-website`.
- Mintlify runs `.js` files in no guaranteed order: keep CLItrail in one file.
